No, it's because governments in Australia are all about generating fake surpluses for political reasons and are not interested in evidence-based policy making and budget decisions.
Here's the basic strategy - we run down publically funded services by cutting funding incrementally (or radically) every year. Occasionally for political reasons you give some funding back and announce that is "hey we listened and are building 1 new hospital or school" while in reality we keep cutting funding across the board. As hospital waiting lists grow we can then blame it on immigrants and population growth. We then can argue that "public doesn't work" and privatise by selling these public enterprises to our mates in the private sector, but continuing to make it lucrative by subsidising these services with government funding - the so-called "PPP's", "Public/Private Partnerships". After we retire from parliament our mates reward us by giving us lucrative consulting jobs associated with the industries we just corrupted and sold.
